(1)  Common Unit discount rate is derived by using the appropriate rate to
     calculate a net present value equal to the 09/25/98 closing price of
     $20.75.
(2)  Terminal value is calculated as a perpetuity by dividing 2002E distribution
     by the discount rate.
(3)  The Junior Subordinated and General Partner Unit discount is determined by
     using a 20% liquidity discount for both Units and a 10% control premium for
     a General Partner Unit. The weighted average based upon pro forma Unit
     ownership is a discount of 17%.

  (1)  Acquisition cost is based on the Pro Forma Market Value of Capitalization
       Analysis (Dain Rauscher Wessels Case), (See Petro Historical and Pro
       Forma MVE and MVC Summary on page 25) less Petro's investment in Star.
       The value of Petro's investment in Star is the closing market price of a
       Star Common Unit one day prior to announcement less a structural
       subordination discount of 15% multiplied by Petro's total implied Star
       units.

  (2)  EBITDA excludes Star Gas distributions and non-recurring expenses.

(1) Acquisition cost is based on the Pro Forma Market Value of Capitalization
    Analysis (Dain Rauscher Wessels Case), [See Petro Historical and Pro Forma
    MVE and MVC Summary on page 25] less Petro's investment in Star. The value
    of Petro's investment in Star is the closing market price of a Star Common
    Unit one day prior to announcement less a structural subordination discount
    of 15% multiplied by Petro's implied Star units.
(2) EBITDA excludes Star Gas distributions and non-recurring expenses.

SITUATION ANALYSIS

     ---------------------------------------------------------------------------
     HEATING OIL BUSINESS

     .  Petro remains the dominant force in the heating oil business, selling at
        least 3 times as much as its nearest competitor.

     .  Petro also dominates the acquisition market, acquiring a substantial
        share of all heating oil businesses sold.

     .  While the company has constantly made acquisitions over the last 5
        years, higher than expected attrition rates have resulted in little
        EBITDA growth.

     .  Operational changes which were instituted on a small scale in 1996-1997
        are expected to reduce the attrition rates over the next several years.

     .  It is anticipated that the acquisition market will continue to be strong
        as more owners approach retirement age and capital gain tax relief
        appears in sight.

SITUATION ANALYSIS

     PETRO'S STOCK PERFORMANCE

     .  Petro's stock has been in a steady decline since 1992.

     .  Petro's stock was particularly hard hit as a result of the warm winter
        of 1996-1997.

     .  It is difficult to determine what portion of the stock's performance was
        related to Petro's financial performance and what portion is
        attributable to a lack of research and institutional following and a
        lack of comps.

     .  More importantly, one must question whether or not the operational
        improvement which is expected over the next two years will be reflected
        in a higher stock price.

     .  Furthermore, Petro's ability to pursue accretive acquisitions will
        continue to be limited by capital constraints.

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     PROPANE BUSINESS

     . Large acquisitions have been scarce. Steady stream of mega-acquisitions
       (1994-96) as over $1.5 billion of equity capital has been raised from
       1992-1996.

     . Pricing on all acquisitions has become extremely competitive.

     . Multiples for even small deals have expanded.

     . Wholesale price spike during the 1996-1997 season revealed another level
       of uncertainty, even for those companies (like Star) which profited from
       the spike.

     . Warm winter in the Northeast compounded the problem for many players.

     . The market is starting to question whether propane MLPs are really growth
       vehicles.

     . The market is also starting to question if the weather is ever normal (it
       always seems to be abnormally warm in some section, which more than
       offsets good results elsewhere).

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     STAR'S STOCK PERFORMANCE

     . While Star has performed relatively well, it is difficult for the market
       to assess how much of the performance was related to inventory gains.

     . Star continues to lag behind other MLPs in terms of acquisitions, where
       Star's ability to compete is limited.

       - Management's limited propane experience limits deal flow

       - Geographic concentration limits "blend-in" opportunities

       - Larger and better capitalized players competing for the same assets

- --------------------------------------------------------------------------------

THE TRANSACTION

     ---------------------------------------------------------------------------

     OVERVIEW

     . We believe that a public stock corporation is not the optimal format for
       Petro.

       - No direct comparables

       - Rapid amortization of customer lists results in no earnings

       - Perceived limited growth in heating oil industry

       - Small capitalization results in limited research coverage

     . Furthermore, the leveraged capital structure limits financial flexibility
       and growth opportunities.


     *    AS A RESULT, PETRO'S STOCK HAS NOT PERFORMED WELL AND IS NOT LIKELY TO
          ACHIEVE FULL VALUATION EVEN IF OPERATIONS IMPROVE.

     ---------------------------------------------------------------------------
                                                                               7

- --------------------------------------------------------------------------------

THE TRANSACTION

     ---------------------------------------------------------------------------

     IN ORDER TO ADDRESS THESE VALUATION ISSUES, PETRO SHOULD CONSIDER THE
     BENEFITS OF AN MLP STRUCTURE WHICH CAN BE ACHIEVED THROUGH A MERGER WITH
     STAR GAS

     . MLPs typically trade on a yield basis, which currently translates into a
       9-10x EBITDA multiple vs a 7-8x multiple historically at Petro.

     . The combination of the two companies would result in a sizable MLP
       (approximately $300 million implied equity value) which translates into
       better valuation and greater liquidity.

     . Concurrent with the merger, the issuance of new equity would restructure
       and delever the balance sheet.

     . The new entity would have substantially better access to capital to fund
       future growth.

     *    THE COMBINED ENTITY WOULD HAVE THE INVESTMENT STORY TO ATTRACT
          RESEARCH COVERAGE AND WOULD BENEFIT BOTH PETRO AND STAR GAS SHARE/UNIT
          HOLDERS.

THE TRANSACTION

      --------------------------------------------------------------------------

      THE TRANSACTION INVOLVES TWO SEPARATE STAGES:

      --------------------------------------------------------------------------
      STAGE 1 -- THE EXCHANGE
      --------------------------------------------------------------------------

      PETRO SHAREHOLDERS EXCHANGE THEIR COMMON STOCK FOR STAR GAS MASTER LIMIT
      PARTNERSHIP UNITS AT $4.50/SHARE

      .  Shareholders who hold only Class A shares exchange into Senior
         Subordinated MLP units

      .  Senior Subordinated MLP Units valued at +/- 10% discount to Common
         Units

      .  "Inside" shareholders /(1) /exchange either into Senior Subordinated
         MLP Units or Subordinated Units plus the General Partnership Interest

      .  Senior Subordinated Units offered to "Insiders" will be capped at 3.5
         million Petro shares in order to provide adequate coverage to Star
         Common Units

      .  Subordinated Units valued at +/- 20% discount to Common Units

      .  All Senior Subordinated and Subordinated Units convert to Common Units
         after 3 years of "Earn & Pay" of $2.30 (i.e. increase the MQD on the
         Common Units)
      --------------------------------------------------------------------------

THE TRANSACTION
     ---------------------------------------------------------------------------

     THE TRANSACTION INVOLVES TWO SEPARATE STAGES:

     ---------------------------------------------------------------------------
     STAGE 2 -- THE RECAPITALIZATION
     ---------------------------------------------------------------------------
     APPROXIMATELY $330 MILLION OF PETRO DEBT AND PREFERRED STOCK ARE REFINANCED

     .  Existing issues will be either redeemed, exchanged, defeased or tendered
        for, depending on issue

     .  Approximately $140 million of new Star equity will be raised through the
        sale of Common Units

     .  Approximately $125 million of new, investment grade debt will be issued

STEPS OF THE TRANSACTION AND TAX IMPLICATIONS

   -----------------------------------------------------------------------------

 
                         STEPS OF THE TRANSACTION    


   .  STEP ONE: Star Gas Corp. merges into Petro. Petro obtains from Star Gas
      -------- 
      Corp. the GP units of MLP and OLP and MLP subordinated units. Petro
      transfers the GP units to an LLC. The subordinated units are designated
      Senior Subordinated Units.


   .  STEP TWO: Petro transfers assets to MLP in exchange for additional Senior
      --------
      Subordinated Units so as to have a total number of Senior Subordinated
      Units equal in value to the value of the Petro Class A Common Stock held
      by the public.

   .  STEP THREE: Petro exchanges all LLC shares for an equivalent value of
      ----------
      Class C shares held by Petro insiders.


   .  STEP FOUR: The Petro insiders transfer their remaining Class A and Class C
      ---------
      Stock to the MLP in exchange for Junior Subordinated Units.


   .  STEP FIVE: OLP organized Newco. MLP transfers to OLP and OLP transfer to
      --------- 
      Newco, all Petro shares owned by the MLP, as acquired by MLP from the
      Petro insiders.


   .  STEP SIX: Newco merges with and into Petro. Class A Shares owned by the
      --------
      public are changed into Senior Subordinated Units. Class A and Class C
      shares owned by Newco are canceled. Newco shares owned by OLP are changed
      into Class A Petro shares.



                         CORRESPONDING TAX IMPLICATION

   .  Tax free.


   .  Tax free.


   .  This triggers tax at Petro measured by the value of the LLC shares in
      excess of Petro's basis in them and tax at the Petro insider level
      measured by the value of the LLC shares in excess of their basis in the
      Petro shares surrendered.
      
   .  Tax free.


   .  Tax free.


   .  This step is tax free to Newco and OLP. Petro will recognize gain equal to
      the value of the Senior Subordinated Units in excess of Petro's basis in
      them. The public shareholders will recognize gain (or loss) measured by
      the excess (or deficit) in value of the Senior Subordinated Units as
      compared to their basis in the Petro Class A Common Stock.

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     PROPANE BUSINESS

     . Pricing on all acquisitions has become extremely competitive as over $1.5
       billion of equity has come into the industry since 1994.

     . Large acquisitions have been scarce and multiples for even small deals
       have expanded.

     . Wholesale price spike during the 1996-1997 season revealed another level
       of uncertainty, even for those companies (like Star) which profited from
       the spike.

     . Warm winter in the Northeast compounded the problem for many players.

     . The market is starting to question whether propane MLPs are really growth
       vehicles, as many have failed to demonstrate internal growth.

     . The market is also starting to question if the weather is ever normal (it
       always seems to be abnormally warm in some section, which more than
       offsets good results elsewhere).

SITUATION ANALYSIS

     ---------------------------------------------------------------------------
     STAR CONTINUES TO LAG BEHIND OTHER MLPS IN TERMS OF ACQUISITIONS, WHERE

     .  Larger and better capitalized players compete for the same assets

SITUATION ANALYSIS

     -------------------------------------------------------------------------

     HEATING OIL BUSINESS

     .  Petro remains the dominant force in the heating oil business, selling at
        least 3 times as much as its nearest competitor.

     .  Petro also dominates the acquisition market, acquiring a substantial
        share of all heating oil businesses sold.

     .  While the company has constantly made acquisitions over the last 5
        years, higher than expected attrition rates have resulted in little
        EBITDA growth.

     .  Operational changes which were instituted on a small scale in 1996-1997
        are expected to reduce the attrition rates over the next several years.

     .  It is anticipated that the acquisition market will continue to be strong
        as more owners approach retirement age and capital gain tax relief
        appears in sight.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     PETRO WILL TAKE ADVANTAGE OF FAVORABLE CONDITIONS IN THE HEATING OIL MARKET


     .  Significant competitive advantages.

        -- Industry is populated by thousands of relatively small local family
           owned businesses

        -- Higher concentration of customers than in the propane industry
           creates critical mass

        -- Sufficient financial resources to make key strategic acquisitions

        -- Management openness and ability to modify historical operating
           practices


     .  Consumer attitudes facilitate creation of a brand image.

        -- Utility product that is delivered without affirmative purchase
           decision

        -- 92% of customers do not know competitor's prices

        -- 35% of consumers do not know the name of another heating oil
           company

        -- Only 34% know the name of only one other company (no one specific
           competitor)


     .  Unique size provides significant opportunities.

        -- Engage professional management and achieve efficient organizational
           structure

        -- Enhance MIS and communication technology

        -- Operating and marketing efficiencies

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     ANTICIPATED BENEFITS FROM STRATEGY

     .  Reduced operating costs and increased profitability.

     .  Growth through internal marketing.

     .  Attract new customers.

     .  Retain existing customers.

     .  Improve products and services.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     BY CREATING A BRAND IMAGE, PETRO CAN TARGET A NEW CUSTOMER BASE

     .  Consumers moving into oil heated homes.

     .  Other fuel oil dealers' dissatisfied customers.

        -- Represents 8% to 10% of market

     .  Customers of other nationally branded companies offering home delivered
        products and services.

        -- HFS real estate family of companies (Century 21, ERA, Coldwell 
           Banker)

        -- Security systems

        -- Bottled water

        -- Extermination

        -- Electricity  

        -- Lawn care


     *   CREATING A BRAND IMAGE WOULD PROVIDE PETRO THE OPPORTUNITY TO FILL THE
         VOID IN THE INDUSTRY BY BECOMING THE ONLY CONSUMER-RECOGNIZABLE HEATING
         OIL COMPANY.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     IMPROVE EXISTING CUSTOMER RETENTION


     .  Improve product thereby increasing customer satisfaction and reducing
        triggering events.

        -- Reduce oil runouts

        -- Reduce incomplete and repeat equipment repairs

        -- Provide unique on-time repairs


     .  All employees function as salesmen.


     .  Segmented and unbundled pricing.


     .  Create deeper customer relationships.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     CREATE SEGMENTED AND UNBUNDLED PRICING

     .  Heating equipment repair and maintenance revenues lower than cost.

        -- Bundled with and subsidized by oil price

     .  Unlimited annual service contracts.

     .  Tailor unbundled pricing packages for different customer segments.

        -- Shift charges away from more visible oil to less sensitive equipment 
           repair

        -- Replace unlimited service contracts with co-pay program based on
           usage

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     CREATE DEEPER CUSTOMER RELATIONSHIPS

     .  Offer rationally related products requiring similar operating expertise.

        -- Air conditioning

        -- Electric repair

        -- Plumbing


     .  Create affinity group buying benefits with cross marketing partners.

- -------------------------------------------------------------------------------

THE TRANSACTION

     --------------------------------------------------------------------------

     OVERVIEW


     .    Star's limited size relative to other comparable MLPs restricts both
          its financial flexibility and access to strategic acquisitions.


     .    We believe that a public stock corporation is not the optimal format
          for Petro.

          __   No direct comparables

          __   Rapid amortization of customer lists results in no earnings

          __   Perceived limited growth in heating oil industry

          __   Small capitalization results in limited research coverage


     .    Furthermore, Petro's leveraged capital structure also limits its
          financial flexibility and growth opportunities.

     *    AS A RESULT, STAR GAS TRADES AT A SLIGHT DISCOUNT TO ITS PEERS, WHILE
          PETRO'S STOCK HAS PERFORMED POORLY AND IS NOT LIKELY TO ACHIEVE FULL
          VALUATION EVEN IF OPERATIONS IMPROVE.

     --------------------------------------------------------------------------
                                                                              17

- -------------------------------------------------------------------------------

THE TRANSACTION
     
     --------------------------------------------------------------------------
     
     IN ORDER TO ADDRESS THESE VALUATION ISSUES, STAR GAS SHOULD CONSIDER THE
     BENEFITS OF A MERGER WITH PETRO

     .    The combination of the two companies would result in a sizable MLP
          (approximately $325 million implied equity value) which translates
          into better valuation and greater liquidity.

     .    The new entity would have substantially better access to capital to
          fund future growth.

     .    Concurrent with the merger, the issuance of new equity would
          restructure and delever the balance sheet.

     .    The restructuring would be accretive to distributable cash flow.


     *    THE COMBINED ENTITY WOULD HAVE THE INVESTMENT STORY TO ATTRACT
          RESEARCH COVERAGE AND WOULD BENEFIT BOTH STAR GAS AND PETRO SHARE/UNIT
          HOLDERS.

     A MERGER WITH PETRO WILL RESPOND TO SEVERAL IMPORTANT INVESTOR ISSUES

     --------------------------------------------------------------------------
     Q:  How will the market value the mixed MLP?

     A:  Growth and ability to make distributions are the key considerations for
         valuing an MLP. The merger provides the size, business mix and
         flexibility that investors are seeking. Several diversified MLPs exist
         and perform favorably compared to their peers.

     Q:  The propane industry has low annual growth (1%-2%) versus the heating
         oil industry which is declining (2%-4%) each year. Why should Star
         enter an industry that experiences attrition?

     A:  While propane is a growth industry, there are several larger and better
         capitalized companies that are actively taking advantage of industry
         consolidation. As a result, average acquisition multiples have been bid
         up to 7x EBITDA or higher. On the other hand, Petro is the dominant
         player and leading consolidator in the heating oil market. As a result,
         Petro has averaged 10 acquisitions each year since 1992 at an average
         purchase multiple of approximately 4x EBITDA. As demonstrated below, an
         acquisition at a 4x EBITDA multiple is profitable even taking into
         account attrition:

     Q:   What initiatives is Petro taking to reverse its high attrition?
     A:   Petro's new strategic focus includes:
          -  Attracting new customers through brand imaging
          -  Cross marketing to new and existing customers
          -  Improving customer service
          -  Creating segmented and unbundled pricing
          -  Create deeper customer relationships through marketing related
             services

     Q:   Why would Petro be interested in a merger with Star Gas?

     A:   Premium to market

               -  At $3.15 per share, the exchange represents approximately a
                  20% premium to the market

          Higher valuation multiples

               -  MLPs typically trade at 10-11x EBITDA

          Enhanced growth potential due to greater access to capital

               -  Branding and internal marketing
               -  Improved productivity through capital investment
               -  Acquisitions

          Lower overall cost of capital

               -  New debt at +/- 8% vs. 12% existing debt
               -  Equity capital with limited upside

          Greater size and liquidity

               -  Implied equity market value quintuples to over $325 million

          Greater financial flexibility

               -  Extend maturities through refinancing
               -  Improved covenants due to investment grade rating

STEPS OF THE TRANSACTION AND TAX IMPLICATIONS

     --------------------------------------------------------------------------

                           Steps of the Transaction 


     .  STEP ONE: Star Gas Corp. merges into Petro. Petro obtains from Star Gas
        --------
        Corp. the GP units of MLP and OLP and MLP subordinated units. Petro
        transfers the GP units to an LLC. The subordinated units are designated
        Senior Subordinated Units.

     .  STEP TWO: Petro transfers assets to MLP in exchange for additional
        --------
        Senior Subordinated Units so as to have a total number of Senior
        Subordinated Units equal in value to the value of the Petro Class A
        Common Stock held by the public.

     .  STEP THREE: Petro exchanges all LLC shares for an equivalent value of
        ----------
        Class C shares held by Petro insiders.

     .  STEP FOUR: The Petro insiders transfer their remaining Class A and Class
        ---------
        C Stock to the MLP in exchange for Junior Subordinated Units.

     .  STEP FIVE: OLP organized Newco. MLP transfers to OLP and OLP transfer to
        ---------
        Newco, all Petro shares owned by the MLP, as acquired by MLP from the
        Petro insiders.

     .  STEP SIX: Newco merges with and into Petro. Class A Shares owned by the
        --------
        public are changed into Senior Subordinated Units. Class A and Class C
        shares owned by Newco are canceled. Newco shares owned by OLP are
        changed into Class A Petro shares.


                Corresponding Tax Implication                  

     .  Tax free.                                  
                                                    
                                               
     .  Tax free.                                  
                                               
                                               
     .  This triggers tax at Petro measured by the value of the LLC shares in
        excess of Petro's basis in them and tax at the Petro insider level
        measured by the value of the LLC shares in excess of their basis in the
        Petro shares surrendered.

     .  Tax free.                                     
                                                 
     .  Tax free.                                     
                                                 
     .  This step is tax free to Newco and OLP. Petro will recognize gain equal
        to the value of the Senior Subordinated Units in excess of Petro's basis
        in them. The public shareholders will recognize gain (or loss) measured
        by the excess (or deficit) in value of the Senior Subordinated Units as
        compared to their basis in the Petro Class A Common Stock.

                INTRODUCTION



TRANSACTION     [_]  During 1997, Gas ("Gas" or the "Company") and Oil ("Oil")
PROPOSAL             discussed the idea of a possible business combination by
                     and between Gas and Oil. The series of proposed
                     transactions involved in such combination is referred to as
                     the "Transaction".

A.G. EDWARDS'   [_]  A.G. Edwards & Sons, Inc. ("A.G. Edwards") has been engaged
ENGAGEMENT           by the Special Committee (the "Special Committee") of the
                     Board of Directors of Gas (the "Board") to act as its
                     financial advisor with respect to the Transaction and to
                     issue to the Board an opinion as to the fairness, from a
                     financial point of view, to the common unitholders of Gas
                     who are not affiliated with Oil (the "Common Unitholders"),
                     of the Transaction (the "Fairness Opinion").

                [_]  The preparation of a fairness opinion is not susceptible to
                     partial analyses or summary. In rendering its Fairness
                     Opinion, A.G. Edwards will apply its judgment to a variety
                     of complex analyses and assumptions. A.G. Edwards may give
                     various analyses more or less weight than other analyses,
                     and may deem various assumptions more or less probable than
                     other assumptions. The assumptions made and the judgments
                     applied by A.G. Edwards in rendering its opinion are not
                     readily susceptible to description beyond that set forth in
                     the written text of the Fairness Opinion itself.

                                                                          Page 1

                (continued)


NATURE OF       [_]  A.G. Edwards relied upon and assumed, without independent
INFORMATION          verification, the accuracy and completeness of all
REVIEWED AND         financial and other information publicly available, or
PRESENTED            furnished to, or otherwise discussed with A.G. Edwards
                     including financial statements and financial projections,
                     as provided by management of Gas and Oil and Oil's
                     financial advisor. With respect to financial projections
                     and other information provided to or otherwise discussed
                     with A.G. Edwards, A.G. Edwards assumed and was advised by
                     the senior management of Gas and Oil, respectively, that
                     such projections and other information were reasonably
                     prepared on a basis that reflects the best currently
                     available estimates and judgments of the senior management
                     of Gas and Oil, respectively, as to the expected future
                     financial performance of Gas and Oil, in each case on a
                     stand-alone basis and after giving effect to the
                     Transaction. A.G. Edwards was not engaged to, and did not,
                     independently verify the information provided and performed
                     no audit of assets or liabilities and no independent
                     appraisal of assets or liabilities of either Gas or Oil.
                     A.G. Edwards has relied upon the assurances of the
                     management of Gas and Oil that they are not aware of any
                     facts that would make such information inaccurate or
                     misleading.


                [_]  In performing its analyses, A.G. Edwards made numerous
                     assumptions with respect to the propane distribution
                     industry and the home heating oil distribution industry,
                     and general business and economic conditions which are
                     beyond the control of Gas and Oil. The analyses performed
                     by A.G. Edwards are not necessarily indicative of actual
                     values or actual future results, which may be significantly
                     more or less favorable than suggested by such analyses.
                     Such analyses were prepared solely as part of A.G. Edwards'
                     Preliminary Report to the Special Committee.

(a)  The number of GP units issued reflect the assumption of a 6,587 common unit
     equity offering to refinance certain of the assumed Oil debt.  Hence, the
     number of GP units reflected in the pro forma column do not equal 2% of the
     pro forma outstanding units shown above but do equal exactly 2% of the pro
     forma units outstanding on a post financing basis.

DISCOUNTED CASH
FLOW ANALYSIS       [_]  A.G. Edwards calculated the implied present value of
                         estimated unlevered free cash flows for Gas on both a
                         stand-alone and pro forma basis (See Appendix J --
                         "Discounted Cash Flow Analysis").

                    [_]  Key assumptions used in the analysis were:

                         -    Oil maintaining a flat 4.1% attrition rate;
                              relatively no margin improvement; and completing
                              $30 million in acquisitions each year at a 4.75x
                              EBITDA multiple.

                         -    A 7.9% weighted average cost of capital for both
                              cases. (See Appendix B, page 24 and Appendix K,
                              page 57).

                         -    A 10.2x terminal EBITDA multiple, representing the

                    PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE



                    [_]  A.G. Edwards has initiated a full diligence review of
                         Oil and has updated its earlier reviews of Gas,
                         including: visits to corporate headquarters; meetings
                         with senior operations and financial officers; review
                         of financial statements, projections, documents and
                         information; evaluation and revision of alternative
                         modeling of the Transaction with Oil's financial
                         advisor; visit to Long Island calling center and
                         meeting with Oil's former consultant and now Vice
                         President; meeting with A.G. Edwards' equity research
                         analyst covering MLP's; and other relevant inquiries
                         regarding operations, acquisitions, financings and
                         other matters.

                    [_]  A.G. Edwards preliminary diligence and work has
                         resulted in certain tentative conclusions and
                         observations regarding Oil and Gas which differ from
                         its original expectations and perceptions, including:

                         -  the anemic heating season in first quarter of
                            calendar 1998 had a greater adverse impact on Gas
                            than on Oil;

                         -  Oil has made strides to implement key portions of
                            Oil's plan and the McKinsey report, including
                            corporate identification, customer communications
                            and implementation of a service culture,
                            regionalization, cross marketing arrangements and
                            rationalization of the management team;

                         -  although the El Nino affect distorted the first
                            quarter of 1998, Oil's attrition was moderated and
                            its pricing strategy was enhanced; and

                         -  Gas has demonstrated an ability to make propane
                            acquisitions on a tuck-in and market expansion
                            basis, and has already agreed to acquire a heating
                            oil business.

                                                                         Page 18

                    PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE
                    (continued)



                    [_]  Although A.G. Edwards does not presently have an
                         adequate basis to form any opinion regarding the
                         Transaction, A.G. Edwards does recommend that the
                         Special Committee and its advisors proceed with its
                         careful consideration and evaluation of the proposed
                         Transaction.

                    [_]  A.G. Edwards requests that Joel Swanson, Esq. and Baker
                         & Botts, LLP consult with Oil's attorneys regarding the
                         proposed resolution of the myriad of legal issues
                         involving tax, partnership and corporate compliance and
                         the timing of the documentation of the Transaction in
                         terms of definitive agreements, proxy statements and
                         the like.

                    [_]  A.G. Edwards perceives Gas as taking appropriate steps
                         to assure procedural fairness of the Transaction
                         including the appointment of the Special Committee, the
                         engagement of counsel and financial advisor and the
                         approval of the Transaction by the majority of
                         Unitholders. The Special Committee should consider
                         whether Oil should be obligated to take parallel action
                         to assure procedural fairness.

                                                                         Page 19

                    PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE
                    (continued)



                    [_]  A.G. Edwards suggests that the Special Committee's
                         consideration of substantive fairness to the Common
                         Unitholders should include an evaluation by the Special
                         Committee and its advisors of:

                         -  whether Gas' partnership agreement should be amended
                            to raise the future required minimum quarterly
                            distribution ("MQD") for common unitholders and, if
                            so, by how much and for what period(s);

                         -  whether the $3.15 exchange ratio should be lowered
                            and, if so, by how much;

                         -  whether the definitive agreements should be drafted
                            consistent with the PaineWebber models so that any
                            excess funds expended by Oil for debt refinancings
                            and the Transaction fees in general should
                            automatically reduce the aggregate consideration
                            paid by Gas for the acquisition of Oil by an equal
                            amount;

                         -  whether cash balances should be set aside for (a)
                            the funding of any unearned MQD to be paid to the
                            new unitholders, (b) the funding of Gas' surplus
                            balance to account for the addition of new
                            outstanding units, and (c) the funding of any off-
                            balance sheet liabilities, such as pension or tax;

                         -  whether cash payments should be required for the
                            issuance of new general partner interests and, if
                            so, by how much; and

                         -  such other issues suggested by the members of the
                            Special Committee and its counsel.


                    [_]  A.G. Edwards recommends that the Special Committee
                         communicate suggested revisions of the Transaction to
                         management of Oil for their consideration.

                                                                         Page 20

OVERVIEW OF OIL


[_]  Oil is the largest retail distributor of home heating oil in the United
     States, serving approximately 350,000 customers in the Northeast and Mid-
     Atlantic states, including the metropolitan areas of Baltimore, Boston, New
     York City and Washington, D.C.


[_]  Since 1979 Oil has been the principal consolidator in the industry, having
     acquired 188 retail heating oil distributors. As a result of these
     acquisitions, heating oil volume sold has increased from 59.4 million
     gallons in 1980 to 410.3 million gallons in 1997.


[_]  Despite Oil's size, its customer base represents only approximately 5% of
     the residential home heating oil customers in the Northeast, uniquely
     positioning the company to continue its strategy of growth through
     acquisitions.


[_]  Oil's strongest competitive advantage is clearly its size, particularly in
     relation to its competitors. Oil's size provides it significant
     opportunities not afforded to most of the industry's small, local, family-
     owned businesses. These opportunities include attracting and retaining a
     professional management team, accessing and maintaining the latest
     developments in computer and communications technology, and achieving
     significant operating and marketing efficiencies.


[_]  Oil's primary goals currently include: reducing operating costs and
     increasing profitability; reducing customer attrition through a focus on
     attracting new customers (better structured, upgraded sales force, brand
     image, cross marketing agreements) and retaining existing customers
     (improving service and having all employees function as salespeople); and,
     given the financial wherewithal, exploit its ability to further consolidate
     the home heating oil market.

                                                                          Page 1

FOR DISCUSSION PURPOSES ONLY                                          5/4 DRAFT
                           PRELIMINARY STATUS REPORT
                              BOARD OF DIRECTORS
                            STAR GAS PARTNERS, L.P.

     Petro management and its advisors have been working on a proposed
transaction between Petro and Star for over a year. Star Committee has engaged
Baker & Botts, LLP as its counsel and A.G. Edwards & Sons, Inc. as its financial
advisor. After one month of preliminary due diligence and review, the Committee
and its advisors better understand and appreciate the complexity of the proposed
transaction and the amount of hard work and creativity dedicated to this
proposal.

     During the past year, both parties have experienced management changes and
adverse weather conditions. During this period, Petro has suspended its common
dividends and its publicly held common shares have traded down. Star's publicly
held common units have traded flat to slightly up, but Star has made
distributions to its common unitholders and its subordinated unitholders (that
is, Petro) even though such distributions exceeded distributable cash flow (that
is, Star returned capital). The Star Committee notes that Petro's capital
constraints have effectively eliminated its historic acquisition program while
Star has demonstrated a far more viable acquisition program.

     In light of these and other significant changes in relative performance,
market conditions and strategic rationale for the proposed transaction, the Star
Committee (after considering the preliminary report of A.G. Edwards and
consulting with counsel), proposes a re-examination, restructuring and repricing
of the proposed transaction between Petro and Star.

     Subject to further diligence and assuming no material adverse changes in
the parties or in market conditions, the Star Committee proposes:

     (A)  Star Partnership Agreement. Appropriate steps should be initiated
          --------------------------                                       
          to amend the Star Partnership Agreement as of the closing date
          (assumed to be September 30, 1998) in order to:

          (A-1) raise the future required minimum quarterly distribution ("MQD")
                for common unitholders from $2.20 per annum to $2.30 per annum;

          (A-2) authorize a new class of senior subordinated units which shall
                be junior to all present and future common units, but senior to
                the present subordinated units; and

          (A-3) prohibit the payment of any future distributions to senior
                subordinated unitholders and to subordinated unitholders except
                from net distributable cash
<PAGE>
 
                flow available for such period after first paying MQD to the
                common unitholders for such period plus any cumulative common
                unit arrearages.

     (B)  Definitive Transaction Agreement. A draft of the definitive
          --------------------------------   
          transaction agreement should be prepared by Petro for Star Committee's
          careful consideration (and for future submission to the Board of
          Directors and common unitholders of Star and to the Board of Directors
          and shareholders of Petro for approval) setting forth the following
          steps:

          (B-1) At closing of the Transaction, Star shall be obligated to pay to
                Petro or assume from Petro a "Maximum Aggregate Consideration"
                of [$390 million] consisting of (A) the total consideration paid
                to Petro's common shareholders calculated at [26,563,000] Petro
                common shares at [$ _________] per share; (B) the principal
                amount of Petro's total debt and preferred stock outstanding
                just prior to closing and any refinancing of such debt or
                preferred stock; and (C) any premiums paid above and beyond the
                principal amount of such debt and preferred stock to redeem,
                exchange, defease or otherwise cancel these liabilities. In
                addition, the distributions made to the Petro common
                shareholders and the refinancing of any assumed debt or
                preferred stock may not result in more than [10,300,000] common
                units outstanding at closing and must result in at least [$125
                million] of new debt carrying an interest rate of no greater
                than [8.50%] having been closed prior to, or simultaneous with,
                the closing of this Transaction.

          (B-2) Prior to the closing of the Transaction, in return for the
                Maximum Aggregate Consideration defined in (B-1), Petro shall
                represent, warrant and agree that:

                (A) Petro shall set up appropriate reserves and fund the
                    following:

                    (1)  off-balance sheet pension liabilities of [$5 million],
                    (2)  off-balance sheet tax liabilities relating to Pearl of
                         [$3.5 million],
                    (3)  surplus cash available for distributions equal to
                         [$1.10] per new common unit issued,
                    (4)  all of the Transaction costs, including the gross
                         spread on Star's new MLP equity and debt; financial
                         advisory fees and fairness opinions for Petro and Star;
                         legal, accounting and printing fees for Petro and Star;
                         all exchange and solicitation fees related to the
                         retirement or redemption of Petro's debt and preferred
                         stock; all appraisals and environmental reports; all
                         rating agencies and bank fees; and all other out-of-
                         pocket costs and expenses associated with the
                         Transaction, and
                    (5)  any "Unearned MQD" monies that Petro wishes to have
                         available for payment to senior subordinated or
                         subordinated unitholders following the closing of the
                         Transaction.

                (B) Petro shall have no borrowed money debt of any kind
                    outstanding other than any such amounts included in (B-1);
<PAGE>
 
                (C) Petro shall have no preferred stock of any kind outstanding
                    other than any such amounts included in (B-1);

                (D) Petro shall have transferred to Star a minimum of
                    [2,000,000] of its subordinated units free and clear for
                    cancellation;

                (E) Petro shall have a minimum balance of cash of [$500,000], a
                    positive working capital balance (subject to further due
                    diligence), and a total common shareholders' deficit on its
                    balance sheet of no greater than [$_______million], all as
                    of the closing.

          (B-3) In the event Petro is unable or unwilling to represent and
                warrant each of the matters set forth in (B-2), then the Maximum
                Aggregate Consideration set forth in (B-1) shall be reduced on a
                dollar-for-dollar basis.

Summary of Transaction
Pro Forma Gas Units Outstanding
(in thousands)

To simplify the         
complexity of the steps 
in the Transaction,     
A.G. Edwards prepared   
a summary of its        
understanding.       

[_]  There are currently 6,355 Gas units outstanding comprised of 3,832 common
     units, 2,396 subordinated units and 127 general partner ("GP") units. The
     subordinated units and GP units are assets of Oil.

[_]  There are currently 26,563 shares of Oil common stock outstanding,
     comprised of public shareholders and "insiders." The public holds 17,160
     Class A shares. The "insiders" hold 9,404 shares which include 6,795 Class
     A shares, 11 Class B shares and 2,598 Class C shares.

[_]  Each shareholder of Oil will receive a certain number of units in Gas such
     that the implied consideration paid for each Oil share is $2.00.

[_]  The publicly held 17,160 Class A shares will receive .1000 shares of newly
     created senior subordinated units (1,716 units in total) with an implied
     value of $20.00/unit. This represents an implied purchase price of
     $2.00/share for an implied total purchase price of $34.3 million.

[_]  The "insiders" of Oil, who hold a total of 9,404 shares (comprised of A, B
     and C shares) will also receive $2.00/share for a total of $18.8 million.
     The consideration received by these shareholders will be funded by:

     - (1) the distribution of existing units of Gas which are currently owned
           by Oil
           [_] all of the 127 GP units owned by Oil will be given as
               consideration at an implied value of $21.62/unit, for a total of
               $2.7 million.
           [_] 373 of the 2,396 subordinated units owned by Oil will be given as
               consideration at an implied value of $16.58/unit, for a total of
               $6.2 million.
     - (2) the distribution of newly-created units of Gas
           [_] to fund the remaining $9.9 million of the $18.8 million due to
               the Oil "insiders", Gas will issue 350 newly-created senior
               subordinated units and 133 newly-created GP units. The implied
               values for these new units are $20.00 and $21.62, respectively.

                                                                          Page 8

Summary of Transaction
Pro Forma Gas Units Outstanding
(in thousands)
(continued)

[_]  Of the 2,396 Subordinated units and 127 GP units owned by Oil, only 2,023
     subordinated units will not have been used as consideration paid to the
     "inside" Oil shareholders. Hence, these 2,023 subordinated units will be
     retired by Gas. A.G. Edwards has assumed that the implied value of these
     units are $16.58/unit for a total retired value of approximately $33.5
     million.

                                                                          Page 9

(a)  The number of GP units issued reflect the assumption of a 6,461 common unit
     equity offering to refinance certain of the assumed Oil debt.  Hence, the
     number of GP units reflected in the pro forma column do not equal 2% of the
     pro forma outstanding units shown above but do equal exactly 2% of the pro
     forma units outstanding on a post financing basis.

                           PRELIMINARY STATUS REPORT
                              BOARD OF DIRECTORS
                            STAR GAS PARTNERS, L.P.

     Petro management and its advisors have been working on a proposed
transaction between Petro and Star for over a year. Star Committee has engaged
Baker & Botts, LLP as its counsel and A.G. Edwards & Sons, Inc. as its financial
advisor. After one month of preliminary due diligence and review, the Committee
and its advisors better understand and appreciate the complexity of the proposed
transaction and the amount of hard work and creativity dedicated to this
proposal.

     During the past year, both parties have experienced management changes and
adverse weather conditions. During this period, Petro has suspended its common
dividends and its publicly held common shares have traded down. Star's publicly
held common units have traded flat to slightly up, but Star has made
distributions to its common unitholders and its subordinated unitholders (that
is, Petro) even though such distributions exceeded distributable cash flow (that
is, Star returned capital). The Star Committee notes that Petro's capital
constraints have effectively eliminated its historic acquisition program while
Star has demonstrated a far more viable acquisition program.

     In light of these and other significant changes in relative performance,
market conditions and strategic rationale for the proposed transaction, the Star
Committee (after considering the preliminary report of A.G. Edwards and
consulting with counsel), proposes a re-examination, restructuring and repricing
of the proposed transaction between Petro and Star.

     Subject to further diligence and assuming no material adverse changes in
the parties or in market conditions, the Star Committee proposes:

     (A)  Star Partnership Agreement. Appropriate steps should be initiated to
          --------------------------
          amend the Star Partnership Agreement as of the closing date (assumed
          to be September 30, 1998) in order to:

          (A-1)  raise the future required minimum quarterly distribution
                 ("MQD") for common unitholders from $2.20 per annum to $2.30
                 per annum;

          (A-2)  authorize a new class of senior subordinated units which shall
                 be junior to all present and future common units, but senior to
                 the present subordinated units; and

          (A-3)  prohibit the payment of any future distributions to senior
                 subordinated unitholders and to subordinated unitholders except
                 from net distributable cash
<PAGE>
 
                 flow available for such period after first paying MQD to the
                 common unitholders for such period plus any cumulative common
                 unit arrearages.

     (B)  Definitive Transaction Agreement. A draft of the definitive 
          --------------------------------  
          transaction agreement should be prepared by Petro for Star Committee's
          careful consideration (and for future submission to the Board of
          Directors and common unitholders of Star and to the Board of Directors
          and shareholders of Petro for approval) setting forth the following
          steps:

          (B-1)  At closing of the Transaction, Star shall be obligated to pay
                 to Petro or assume from Petro a "Maximum Aggregate
                 Consideration" of [$390 million] consisting of:

                 (A)  The issuance of 6,400 new common units at a price per
                      common unit of [$______]. The gross spread on this
                      offering shall not exceed 5.0%.
                 (B)  The issuance of $125,000 of new debt. The gross spread on
                      this offering shall not exceed 3.0%.
                 (C)  The principal amount of all of Petro's outstanding debt
                      and preferred stock of at closing, less the value of
                      Petro's cash balance at closing.
                 (D)  The issuance of no greater than 2,100 new senior
                      subordinated units. The value of such units is assumed to
                      equal $20.00 per unit.
                 (E)  The outstanding balance of subordinated units at closing.
                      The value of such units is assumed to equal $16.58 per
                      unit.
                 (F)  The outstanding balance of GP units, which shall be no
                      greater than 2% of all outstanding units. The value of
                      such units is assumed to equal [$21.62] per unit.

          (B-2)  Consideration paid to Petro's common shareholders shall consist
                 only of the senior subordinated, subordinated and GP units
                 included in (B-1)(D), (B-1)(E) and (B-1)(F).

          (B-3)  Prior to the closing of the Transaction, in return for the
                 Maximum Aggregate Consideration defined in (B-1), Petro shall
                 represent, warrant and agree that:

                 (A)  Petro shall set up appropriate reserves and fund the
                      following:

                      (1)  surplus cash available for distributions equal to
                           [$1.10] per new common unit issued,
                      (2)  excluding only the gross spreads on the new MLP
                           equity and debt offerings, all other Transaction
                           costs, including financial advisory fees and fairness
                           opinions for Petro and Star; legal, accounting and
                           printing fees for Petro and Star; all exchange and
                           solicitation fees related to the retirement or
                           redemption of Petro's debt and preferred stock; all
                           appraisals and environmental reports; all rating
                           agencies and bank fees; and all other out-of-pocket
                           costs and expenses associated with the Transaction,
                           and
<PAGE>
 
                      (3)  any "Unearned MQD" monies that Petro wishes to have
                           available for payment to senior subordinated or
                           subordinated unitholders following the closing of the
                           Transaction. 

                 (B)  Petro shall have no borrowed money debt of any kind
                      outstanding other than any such amounts included in (B-1);

                 (C)  Petro shall have no preferred stock of any kind
                      outstanding other than any such amounts included in (B-1);

                 (D)  Petro shall have a minimum balance of cash of [$500,000],
                      a positive working capital balance (subject to further due
                      diligence), and a total common shareholders' deficit on
                      its balance sheet of no greater than [$______ million],
                      all as of the closing.

          (B-4)  In the event Petro is unable or unwilling to represent and
                 warrant each of the matters set forth in (B-3), then the
                 Maximum Aggregate Consideration set forth in (B-1) shall be
                 reduced on a dollar-for-dollar basis.

                                  PROPOSAL TO
                             THE SPECIAL COMMITTEE
                            STAR GAS PARTNERS, L.P.


     Subject to further diligence and assuming no material adverse changes in
 Star or Petro, or in market conditions, A.G. Edwards proposes:

     (A)  Increase Common Unit Distribution Payments. Simultaneous with the
          ------------------------------------------
          closing date, the quarterly distribution for common unitholders shall
          be raised from $2.20 per annum to $2.30 per annum.

     (B)  Star Partnership Agreement. Appropriate steps should be initiated to
          --------------------------
          amend the Star Partnership Agreement as of the closing date (assumed
          to be September 30, 1998) in order to:

          (B-1)  authorize the creation of new classes of senior subordinated
                 units and deferred partnership units, which shall be junior to
                 all present and future common units, but senior to the present
                 subordinated units;

          (B-2)  prohibit the payment of any distributions to senior
                 subordinated unitholders and to subordinated unitholders except
                 from net distributable cash flow available for such period
                 after first paying MQD to the common unitholders for such
                 period plus any cumulative common unit arrearages; and

          (B-3)  provide a surplus available for common unit distributions
                 equal to $ 1.10 per new common unit, as part of the Refinancing
                 Transaction, described below.

     (C)  Definitive Transaction Agreement. A draft of the definitive
          --------------------------------
          transaction agreement should be prepared by Petro for The Special
          Committee's careful consideration (and for future submission to the
          Board of Directors and common unitholders of Star and to the Board of
          Directors and shareholders of Petro for approval) setting forth the
          following steps:

          (C-1)  At closing of the Transaction, Star shall be obligated to pay
                 to Petro's common shareholders, subject to the Revision Amount
                 as defined in (C-4) below, the following:

                 (A) 2,718 senior subordinated units of Star;  
                 (B) 524 subordinated units of Star; the balance must be
                     delivered to Star free and clear for retirement;
<PAGE>
 
                 (C) 289 GP units of Star; and
                 (D) 909 deferred partnership units of Star, convertible into
                     senior subordinated units with a trigger relating to the
                     financial performance of Petro only.

          (C-2)  The Closing shall be contingent upon the successful completion
                 of the following (collectively, the "Refinancing Transaction"):

                 (A) The issuance of 6,588 new common units at a gross spread of
                     no greater than 5.0%, and
                 (B) The issuance of $125,000 new debt at a gross spread of no
                     greater than 3.0%

                 The use of proceeds of the Refinancing Transaction shall be
                 solely to refinance certain of the outstanding indebtedness
                 assumed from Petro.

          (C-3)  Prior to the closing of the Transaction, Petro shall represent,

                 (B) If the cumulative amount of all revisions, taken as a
                     whole, is greater than zero, then the Revision Amount will
                     be equal to the cumulative amount of all revisions, taken
                     as a whole.

TRANSACTION PROPOSAL    [  ]   During 1997, Gas ("Gas" or the "Company") and Oil
                               ("Oil") discussed the idea of a possible business
                               combination by and between Gas and Oil. The
                               series of proposed transactions involved in such
                               combination is referred to as the "Transaction".

A.G. EDWARDS'           [  ]   A.G. Edwards & Sons, Inc. ("A.G. Edwards") has
                               been engaged by the Special Committee (the
                               "Special Committee") of the Board of Directors of
                               Gas (the "Board") to act as its financial advisor
                               with respect to the Transaction and to issue to
                               the Board an opinion as to the fairness, from a
                               financial point of view, to the common
                               unitholders of Gas who are not affiliated with
                               Oil (the "Common Unitholders"), of the
                               Transaction (the "Fairness Opinion").

                        [  ]   The preparation of a fairness opinion is not
                               susceptible to partial analyses or summary. In
                               rendering its Fairness Opinion, A.G. Edwards will
                               apply its judgment to a variety of complex
                               analyses and assumptions. A.G. Edwards may give
                               various analyses more or less weight than other
                               analyses, and may deem various assumptions more
                               or less probable than other assumptions. The
                               assumptions made and the judgments applied by
                               A.G. Edwards in rendering its opinion are not
                               readily susceptible to description beyond that
                               set forth in the written text of the Fairness
                               Opinion itself.

                                                                          Page 1

NATURE OF INFORMATION    [ ]   A.G. Edwards relied upon and assumed, without
REVIEWED AND PRESENTED         independent verification, the accuracy and
                               completeness of all financial and other
                               information publicly available, or furnished to,
                               or otherwise discussed with A.G. Edwards
                               including financial statements and financial
                               projections, as provided by management of Gas and
                               Oil and Oil's financial advisor. With respect to
                               financial projections and other information
                               provided to or otherwise discussed with A.G.
                               Edwards, A.G. Edwards assumed and was advised by
                               the senior management of Gas and Oil,
                               respectively, that such projections and other
                               information were reasonably prepared on a basis
                               that reflects the best currently available
                               estimates and judgments of the senior management
                               of Gas and Oil, respectively, as to the expected
                               future financial performance of Gas and Oil, in
                               each case on a stand-alone basis and after giving
                               effect to the Transaction. A.G. Edwards was not
                               engaged to, and did not, independently verify the
                               information provided and performed no audit of
                               assets or liabilities and no independent
                               appraisal of assets or liabilities of either Gas
                               or Oil. A.G. Edwards has relied upon the
                               assurances of the management of Gas and Oil that
                               they are not aware of any facts that would make
                               such information inaccurate or misleading.

                         [ ]   In performing its analyses, A.G. Edwards made
                               numerous assumptions with respect to the propane
                               distribution industry and the home heating oil
                               distribution industry, and general business and
                               economic conditions which are beyond the control
                               of Gas and Oil. The analyses performed by A.G.
                               Edwards are not necessarily indicative of actual
                               values or actual future results, which may be
                               significantly more or less favorable than
                               suggested by such analyses. Such analyses were
                               prepared solely as part of A.G. Edwards'
                               Preliminary Report to the Special Committee.

Summary of Transaction
Pro Forma Gas Units Outstanding
(in thousands)

To simplify the complexity of the steps in the Transactions, A.G. Edwards 
prepared a summary of its understanding.


[_]     There are currently 6,355 Gas units outstanding comprised of 3,832
        common units, 2,396 subordinated units and 127 general partner ("GP")
        units. The subordinated units and GP units are assets of Oil.

[_]     There are currently 26,563 shares of Oil common stock outstanding,
        comprised of public shareholders and "insiders." The public holds 17,160
        Class A shares. The "insiders" hold 9,404 shares which include 6,795
        Class A shares, 11 Class B shares and 2,598 Class C shares.

[_]     Each shareholder of Oil will receive a certain number of units in Gas
        such that the implied consideration paid for each Oil share is $2.50.
        Additionally, each shareholder will receive a certain number of deferred
        partnership units ("DPUs") such that if each unit is converted at the
        earliest possible time, then each shareholder will receive an additional
        $0.65 per share in future value.

[_]     The publicly held 17,160 Class A shares will initially receive .1316
        shares of newly created senior subordinated units (2,258 units in total)
        with an implied value (per PaineWebber) of $19.00/unit. This represents
        an implied purchase price of $2.50/share for an implied total purchase
        price of $42.9 million.

[_]     The "insiders" of Oil, who hold a total of 9,404 shares (comprised of A,
        B and C shares) will also initially receive an implied purchase price of
        $2.50/share for a total of $23.5 million. The consideration received by
        these shareholders will be funded by:

        -  (1) the distribution of existing units of Gas which are currently

                   of $2.8 million.

Summary of Transaction
Pro Forma Gas Units Outstanding
(in thousands)
(continued)

[_]     Of the 2,396 subordinated units and 127 GP units owned by Oil, only
        1,872 subordinated units will not have been used as consideration paid
        to the "inside" Oil shareholders. Hence, these 1,872 subordinated units
        will be retired by Gas. A.G. Edwards has assumed that the implied value
        of these units are the same as the value PaineWebber is placing on the
        subordinated units, which is $16.00/unit, for a total retired value of
        approximately $30.0 million.

                                                                          Page 6

(a)  The number of GP units issued reflects the assumption of a 6,588 common
     unit equity offering to refinance certain of the assumed Oil debt and a 475
     common unit equity offering to finance Gas' acquisitions. Hence, the number
     of GP units reflected in the pro forma column do not equal 2% of the pro
     forma outstanding units shown above but do equal exactly 2% of the pro
     forma units outstanding on a post financing basis.

                              (c) Represents Gas' average price for the period 
                                  divided by Oil's average price for the period.

PREMIUMS PAID ANALYSIS    [_] An analysis of acquisitions of companies whose 
                              stock traded under $5.00 per share (pre-merger) 
                              versus companies that traded over $10.00 per 
                              share (pre-merger) indicates a substantial 
                              difference in the premiums paid.

                          [_] Normal premiums for merger of equal transactions 
                              is -2.5% to 21.2% and normal premiums for

Relative Contribution    [_]  A.G. Edwards reviewed and compared the relative
Analysis                      EBITDA contribution of Gas and Oil to each firms'
                              share of the implied combined firm value. Other
                              measures of relative contribution analysis were
                              non-meaningful.

                         [_]  For Gas' contribution of approximately 34% of the
                              combined entity's EBITDA(a), it will receive
                              approximately 41% of the implied firm value.

          Updated Report to Gas' Special Committee



          A.G. Edwards has continued its diligence reviews of Oil and Gas, has
          exchanged data and views with Oil's advisor, and has further updated
          its earlier views and opinions of the Proposed Transaction. Certain
          additional observations since our last meeting include:

          [_]  Oil continues to perform relatively better than Gas.

               -  Additional cost reductions at Oil should add $4.4 million
                  annually to Oil's ongoing EBITDA.

               -  Oil continues to show improvements in its attrition rate and
                  margin growth. YTD through 3/31/98, Oil's attrition rate was
                  3.3% (4.0% in January, 3.5% in February and 2.8% in March) and
                  its margin growth was 3.7 cents.

               -  Gas continues to experience much slower growth than originally
                  budgeted; management has revised downward its internal growth
                  projections and budget.

               -  Although not yet reflected in the market, Gas is now not
                                                                       ---
                  expecting to earn its $2.20 MQD until possibly 2003.

               -  Upward revisions at Oil and downward revisions at Gas now
                  appear to make the Proposed Transaction more accretive than
                  historically thought; the revisions support a 1999P DCF/share
                  of $2.73, which should easily support the proposed
                  distribution increase from $2.20 to $2.30/unit.

          [_]  Oil's stock price has recently improved while Gas' unit price has
               declined slightly.

               -  Oil's stock price now trades at $2.0625/share vs.
                  $1.5625/share, an increase of 32.0%.

               -  Gas' common unit price now trades at $21.125/unit vs.
                  $22.125/unit, a decrease of 4.5%.

          [_]     An analysis of premiums paid in acquisitions of companies
                  whose stocks trade under $5.00 per share supports the view
                  that such companies generally receive a larger acquisition
                  premium in this inefficient sector of the market. An analysis
                  of transactions since 1996 indicated an average premium of
                  47.3% for companies whose stocks trade under $5.00/share
                  (normal range: 13.5% - 81.0%) compared to an average premium
                  of 33.2% for companies whose stocks trade over $10.00/share
                  (normal range: 10.7% - 55.8%).

                                                                         Page 23

          (continued)


          [_]  Although A.G. Edwards cannot presently provide any opinion
               regarding the Proposed Transaction, A.G. Edwards does recommend
                                                                --------------
               that the Special Committee communicate to Oil and Oil's financial
               advisor that the Committee is willing to move forward with the
               Proposed Transaction as outlined in the "Proposal to Special
               Committee, Star Gas Partners, L.P.," attached hereto in Section
               VI. It is our understanding that Oil respectfully disagrees with
               selected aspects of the proposal.

          [_]  A.G. Edwards recommends that Joel Swanson, Esq. and Baker &
               Botts, LLP consult with Oil's attorneys regarding the proposed
               resolution of the myriad of legal issues involving tax,
               partnership and corporate compliance and the timing of the
               documentation of the Transaction in terms of definitive
               agreements, proxy statements and the like.

                            STAR GAS PARTNERS, L.P.
                               REVISED PROPOSAL

     After careful consideration of the Proposed Transaction and the views 
expressed by Petro and PaineWebber, the Special Committee and its advisors 
recommend that further refinement and evaluation of the Proposed Transaction is 
appropriate.

     Subject to further diligence and assuming no material adverse changes in 
Star or Petro, or in market conditions, the Special Committee proposes that the 
transaction contain the following safeguards for the benefit of Star's common 
unitholders:

     (A)  Star Partnership Agreement. Appropriate steps should be initiated to 
          --------------------------
          amended the Star Partnership Agreement as of the closing date (assumed
          to be September 30, 1998) in order to include as a minimum:

          (A-1)     authorizing the creation of new classes of senior 
                    subordinated units and deferred partnership units, which 
                    shall be junior to all present and future common units;

          (A-2)     prohibiting the payment of any distributions to senior 
                    subordinated unitholders and to subordinated unitholders    
                    except from net distributable cash flow available from the 
                    preceding twelve months after first paying $2.30 per unit 
                    to the common unitholders for such period plus any 
                    cumulative common unit arrearages from prior period(s); and

          (A-3)     providing a surplus available for common unit distributions
                    equal to $1.10 per new common unit, as part of the
                    Refinancing Transaction (described below).

     (B)  Definitive Transaction Agreement. A draft of the definitive 
          --------------------------------
          transaction agreement should be prepared by Petro for Special
          Committee's careful consideration (and for future submission to the
          Board of Directors and common unitholders of Star and to the Board of
          Directors and shareholders of Petro for approval) setting forth at
          least the following steps:

          (B-1)     At closing of the Transaction, Star shall be obligated to 
                    deliver to Petro's common shareholders, subject to 
                    reduction by the Revision Amount as defined in (B-4) below,
                    the following: 
     
                    (A)  2,718,000 senior subordinated units of Star;

<PAGE>
 
               (B)  524,000 subordinated units of Star; the balance must be 
                    delivered to Star free and clear for retirement;
               (C)  289,000 GP units of Star; and
               (D)  909,000 deferred partnership units of Star, convertible into
                    senior subordinated units at 33 1/3% per annum for each year
                    in which Petro's after-tax income contributes accretion to 
                    every Star unit in excess of [$0.50].

        (B-2)  The Closing shall be contingent upon the successful completion of
               the following (collectively, the "Refinancing Transaction"):

               (A)  The issuance of no more than 6,588,000 new common units at a
                    price per unit of at least $21 with a gross spread of no 
                    greater than 5.0%, and
               (B)  The issuance of $125,000,000 new debt with an interest rate 
                    no higher than [8.5%] with a gross spread of no greater than
                    3.0%.

               The use of proceeds of the Refinancing Transaction shall be 
               solely to refinance certain of the outstanding indebtedness 
               assumed from Petro.

        (B-3)  Prior to the closing of the Transaction, Petro shall represent, 
               warrant and agree that:

               (A)  Prior to the Refinancing Transaction, Petro shall have a 
                    balance of debt and preferred stock (at redemption value),
                    less any cash balance in excess of such amounts required in
                    (B-3) (B) below, of no more than $331,367,000.
               (B)  Petro shall have a minimum cash balance of $500,000, a 
                    positive working capital balance, and a total stockholders' 
                    deficit on its balance sheet of no greater than [$__ 
                    million], all as of the Closing.
               (C)  Petro shall set up appropriate reserves and fund all of the 
                    following transactions costs: the gross spread on the 
                    issuance of the new debt referred to in (B-2) (B); financial
                    advisory fees and fairness opinions for Petro and Star; 
                    legal, accounting and printing fees for Petro and Star; all
                    exchange and solicitation fees related to the retirement or 
                    redemption of Petro's debt and preferred stock; all 
                    appraisals and environmental reports; all rating agencies 
                    and bank fees; and all other out-of-pocket costs and 
                    expenses associated with the Transaction.

        (B-4)  In the event Petro is unable or unwilling to represent and 
               warrant each of the matters set forth in (B-3), then a Revision
               Amount

<PAGE>
 
               (defined below) will be established. The Revision Amount shall 
               reduce, on a dollar-for-dollar basis, the number of senior 
               subordinated units of Star to be delivered to Petro's common 
               shareholders as set forth in (B-1)(A) with each senior 
               subordinated unit deemed to equal $19/unit. 

               The Revision Amount shall be the difference between the net sum 
               of monies referred to in (B-3) (A), (B) and (C) above that are
               transferred to Star at Closing compared to the defined or stated 
               amounts in (B-3). If the Revision Amount is negative, then the 
               Revision Amount will be considered to equal zero.

               In the event the Revision Amount exceeds [$__million], Star shall
               not be obligated to proceed.

        (B-5)  Prior to the Closing of the Transaction, Petro shall not declare
               or distribute any cash dividends to its common shareholders.

                               SPECIAL COMMITTEE               DRAFT 5/26/98
                            STAR GAS PARTNERS, L.P.
                               REVISED PROPOSAL

     After careful consideration of the Proposed Transaction and the views 
expressed by Petro and PaineWebber, the Special Committee and its advisors 
recommend that further refinement and evaluation of the Proposed Transaction is 
appropriate.

     Subject to further diligence and assuming no material adverse changes in 
Star or Petro, or in market conditions, the Special Committee proposes that the 
transaction contain the following safeguards for the benefits of Star's common 
unitholders;

     (A)  Star Partnership Agreement.   Appropriate steps should be initiated
          --------------------------
          to amend the Star Partnership Agreement as of the closing date
          (assumed to be September 30, 1998) in order to include as a minimum:

          (A-1)  authorizing the creation of new classes of senior subordinated
                 units and deferred partnership units, which shall be junior to
                 all present and future common units;

          (A-2)  prohibiting the payment of any distributions to senior
                 subordinated unitholders and to subordinated unitholders except
                 from net distributable cash flow available from the preceding
                 twelve months after first paying $2.30 per unit to the common
                 unitholders for such period plus any cumulative common unit
                 arrearages from prior period(s); and

          (A-3)  providing a surplus available for common unit distributions
                 equal to $1.10 per new common unit, as part of the Refinancing
                 Transaction (described below).

     (B)  Definitive Transaction Agreement. A draft of the definitive
          --------------------------------
          transaction agreement should be prepared by Petro for the Special
          Committee's careful consideration (and for future submission to the
          Board of Directors and common unitholders of Star and to the Board of
          Directors and shareholders of Petro for approval) setting forth at
          least the following steps:

          (B-1)  At closing of the Transaction, Star shall be obligated to 
                 deliver to Petro's common shareholders the following:

                 (a)  2,718,000 new senior subordinated units of Star;
                 (b)  524,000 subordinated units of Star; the balance must be 
                      delivered to Star free and clear for retirement;

<PAGE>
 
               (c)  289,000 GP units of Star; and

               (d)  909,000 new deferred partnership units of Star, convertible
                    into senior subordinated units at 33 1/3% per annum for each
                    year in which Petro's after-tax income contributes accretion
                    to every Star unit in excess of $0.50.

                            STAR GAS PARTNERS, L.P.
                               REVISED PROPOSAL

     Subject to further due diligence, and assuming no material adverse changes 
in Star, Petro or market conditions, the Special Committee of Star proposes that
an acquisition of Petro by Star contain the following:

     (A)  Star Partnership Agreement. Appropriate steps should be initiated to
          --------------------------
          amend the Star Partnership Agreements as of the closing date in order
          to include, as a minimum:

          (A-1)  authorizing the creation of a new class of senior subordinated
                 units, which shall be junior to all present and future common
                 units;

          (A-2)  subordinating the GP units in terms of their distribution
                 rights to equal those of the subordinated units, which in turn
                 shall be junior to all present and future common and senior
                 subordinated units;

          (A-3)  increasing the MQD and actual distribution to $2.30 per unit on
                 an annualized basis;

          (A-4)  prohibiting the payment of any distributions to senior
                 subordinated, subordinated and GP units from anything but
                 Adjusted Operating Surplus (i.e. what is "earned") over the
                 latest twelve months after first paying the MQD per unit to the
                 common unitholders for such period plus any cumulative common
                 units arrearages from prior period(s); and

          (A-5)  an increase in the Operating Surplus basket equal to:

                    $6.0 million                  New common units       
                    ------------
                    Common units                  issued in the          
                    Outstanding as of             Refinancing            
                    7/27/98                x      Transaction            
                                                                          

     (B)  Definitive Transaction Agreement. A draft of the definitive
          --------------------------------
          transaction agreement should be prepared by Petro for the Special
          Committee's careful consideration (and for future submission to the
          Board of Directors and common unitholders of Star and to the Board of
          Directors and shareholders of Petro for approval) setting forth at
          least the following steps:

<PAGE>
 
        (B-1)  At closing of the transaction, Star shall be obligated to deliver
               to Petro's common shareholders the following:

               (a)  2,809,000 new senior subordinated units of Star;

               (b)  537,000 subordinated units of Star; the balance must be 
                    delivered to Star free and clear for retirement;

               (c)  GP units of Star equaling no greater than 2% of the total 
                    units outstanding at closing, and

               (d)  special distribution rights limited to an aggregate of
                    909,000 senior subordinated units. A special distribution of
                    303,000 senior subordinated units will be granted to the 
                    senior subordinated, subordinated and GP unitholders each
                    time Petro Accretion (to be subsequently defined) exceeds
                    $0.50 per unit for the latest twelve months. The first test
                    will be twelve months after the closing, and such tests will
                    not be more often than once every twelve months. If the
                    tests are not met within four years after the closing, then
                    the right to earn the special distribution will lapse.

        (B-2)  The closing shall be contingent upon the successful completion of
               the following (collectively, the "Refinancing Transaction"):

               (a)  the issuance of no more than an aggregate of $140 million of
                    new common and/or subordinated units, excluding any
                    overallotment option of no greater than 15% associated with
                    a common unit offering, with a gross spread of no greater
                    than 5.0%; and

               (b)  the issuance of no more than $120 million of new debt with a
                    gross spread of no greater than 3.0%.

               The use of proceeds of the Refinancing Transaction shall be
               solely to refinance certain of the outstanding indebtedness
               assumed from Petro.

               Further, the cost of capital from the equity and debt raised in
               the Refinancing Transaction may not exceed $27.5 million on an
               annual basis. "The cost of capital from the equity and debt
               raised in the Refinancing Transaction on an annual basis" shall
               be calculated as follows: (A) the number of new units issued in
               (B-2)(a) multiplied by $2.30 per unit, plus (B) the amount of new
               debt issued in (B-2)(b) multiplied by the offering yield of such
               new debt.

        (B-3)  Prior to the closing of the transaction, Petro shall represent, 
               warrant and agree that:
<PAGE>
 
          (a)  Prior to the Refinancing Transaction, the sum of the pro forma
               principal amount of Petro debt which is restructured plus the
               redemption/repurchase price of all debt and preferred stock
               redeemed in the transaction (including the value of Petro stock
               issued in connection with the redemption option), less any cash
               balance in excess of such amounts required in (B-3) (b) below,
               shall be no greater than $331,367,000.

        (b)    Petro shall have a minium cash balance of $500,000, a positive
               working capital balance, and a total stockholders' defict on its
               balance sheet on closing if no greater than Maximum Stockholders'
               Deficit (to be subsequently defined based on updated projections
               and anticipated closing dates).

        (c)    Petro shall set up appropriate reserves and fund all of the
               following transactions costs: the gross spread on the issuance of
               the new debt referred to in (B-2) (b); financial advisory fees
               and fairness opinions for Petro and Star; legal, accounting and
               printing fees for Petro and Star; all exchange and solicitation
               fees related to the retirement or redemption of Petro's debt and
               preferred stock; all appraisals and environmental reports; all
               rating agencies and bank fees; and all other out-of-pocket costs
               and expenses associated with the transaction.

        (B-4)  Prior to the closing of the transaction, Petro shall not declare
               or distribute any cash dividends to it common shareholders.

                                 "Financings");

                            -    The withdrawal of Star Gas Corporation as the

                                 and the election of Star Gas LLC as the new
                                 general partner; and

                            -    Amending the Agreement of Limited Partnership
                                 of the Partnership and the Operating

                                 Transaction.

                            Opinion").

                      [_]   The preparation of a fairness opinion is not
                            susceptible to partial analyses or summary. In
                            rendering its Fairness Opinion, A.G. Edwards applied
                            its judgment to a variety of complex analyses and
                            assumptions. A.G. Edwards may have given various
                            analyses more or less weight than other analyses,
                            and may have deemed various assumptions more or less
                            probable than other assumptions. The assumptions
                            made and the judgments applied by A.G. Edwards in
                            rendering its opinion are not readily susceptible to
                            description beyond that set forth in the written
                            text of the Fairness Opinion itself.

                                   A.G. Edwards considered relevant.

NATURE OF INFORMATION        [_]   In rendering its Fairness Opinion, A.G.
REVIEWED AND PRESENTED             Edwards has relied upon and assumed, without
                                   independent verification, the completion of
                                   the Financings and the Transaction in
                                   accordance with the Agreement and Plan of
                                   Merger, and the accuracy and completeness of
                                   all financial and other information, publicly
                                   available, furnished to, or otherwise
                                   discussed with A.G. Edwards for the purposes
                                   of the Fairness Opinion. With respect to
                                   financial projections and other information
                                   provided to or otherwise discussed with A.G.
                                   Edwards, A.G. Edwards assumed and was advised
                                   by the management of the General Partner and
                                   Petro, respectively, that such projections
                                   and other information were reasonably
                                   prepared on a basis that reflects the best
                                   currently available estimates and judgments
                                   of the management of the General Partner and
                                   Petro, respectively. A.G. Edwards did,
                                   however, review numerous sets of projections
                                   for Petro and analyzed what it believed were
                                   certain of the major assumptions embedded
                                   within Petro's projections. A.G. Edwards used
                                   two sets of projections for Petro to perform
                                   its analyses. A.G. Edwards used a set of
                                   projections based on 30-year weather and a
                                   set of projections based on 15-year weather.
                                   The Special Committee did not, however,
                                   engage A.G. Edwards to, and therefore A.G.
                                   Edwards did not, verify the accuracy or
                                   completeness of any such information. A.G.
                                   Edwards has relied upon the assurances of the
                                   management of the General Partner and Petro
                                   that the respective managements are not aware
                                   of any facts that would make such information
                                   inaccurate or misleading.

           INTRODUCTION
           (continued)

              [  ]   In performing its analyses, A.G. Edwards made numerous
                     assumptions with respect to the retail propane distribution
                     industry and the retail home heating oil distribution
                     industry, and general business and economic conditions
                     which are beyond the control of the Partnership and Petro.
                     The analyses performed by A.G. Edwards are not necessarily
                     indicative of actual values or actual future results, which
                     may be significantly more or less favorable than suggested
                     by such analyses. Such analyses were prepared solely as
                     part of A.G. Edwards' analysis of the fairness, from a
                     financial point of view, to the Public Common Unitholders
                     of the Transaction.

              [  ]   This presentation is for the private use of the Special
                     Committee and may not be distributed to any other parties
                     without A.G. Edwards' written permission. THE ANALYSES
                     PRESENTED HEREIN RELATE TO THE FAIRNESS OPINION TO BE
                     ISSUED BY A.G. EDWARDS, BUT DO NOT COMPRISE THE FAIRNESS
                     OPINION.

              [  ]   A.G. Edwards' Fairness Opinion, in any event, is limited to
                     the fairness, from a financial point of view, to the Public
                     Common Unitholders of the Transaction. The Fairness Opinion
                     does not constitute a recommendation to any Public Common
                     Unitholders as to how to vote with respect to the
                     Transaction. The Fairness Opinion does not represent tax or
                     legal advice. The summary description of the analysis
                     described herein, is qualified in its entirety by reference
                     to the full text of the Fairness Opinion.

              [  ]   The Fairness Opinion is necessarily based upon financial
                     and other conditions and circumstances existing and
                     disclosed to it as of October 16, 1998. A.G. Edwards has
                     been requested to update its Fairness Opinion to a date
                     prior to the mailing of the Form S-4 Registration
                     Statements by Petro and the Partnership. No assurance can
                     be given that future market conditions will permit A.G.
                     Edwards to deliver an updated Fairness Opinion.

ASSUMPTIONS    [  ]  In rendering it Fairness Opinion, A.G. Edwards has assumed
                     that the Transaction will be consummated on the terms
                     contained in the Form S-4 Registration Statement and
                     exhibits thereto, including the Agreement and Plan of
                     Merger, the Exchange Agreement, the Amended and Restated
                     Agreement of Limited Partnership and the Conveyance and
                     Contribution Agreements, without any waiver of any material
                     terms or conditions by the Partnership or Petro. The
                     assumption that the Financings are consummated in
                     accordance with the closing conditions of the Agreement and
                     Plan of Merger is a material assumption. 

                                                                          Page 4

SUMMARY OF THE TRANSACTION
PRO FORMA STAR GAS UNITS OUTSTANDING
(in thousands)

  [  ]   There are currently 6,383 Star Gas units outstanding comprised of 3,859
         common units, 2,396 subordinated units and 128 implied general partner
         ("GP") units. The subordinated units and GP units are currently assets
         of Petro.


  [  ]   There are currently 26,574 shares of Petro common stock outstanding
         held by public shareholders and "affiliates." The public holds 14,327
         Class A shares, 11 Class B shares and 282 Class C shares. The
         "affiliates" hold 11,953 shares which include 9,638 Class A shares and
         2,315 Class C shares.


  [  ]   Each shareholder of Petro will receive a certain number of units in
         Star Gas such that the implied consideration paid for each Petro share
         averages $2.43 based on A.G. Edwards' estimates of the value of the
         units being offered to Petro as consideration.


  [  ]   All of the publicly held 14,327 Class A shares and 282 Class C shares,
         and a portion of the "affiliate" held Class A shares (5,243) and Class
         C shares (1,328) will receive .13064 units of newly created senior
         subordinated units for each share (1,908 units to the public and 859
         units to the "affiliates", 2,767 units in total) with an attached
         Contingent Unit ("CU"). See the following page for a discussion of the
         Contingent Units. A.G. Edwards estimates an implied value for these
         units of $18.52/unit. The remaining "affiliates" of Petro not receiving
         senior subordinated units, who hold a total of 5,382 shares, will
         receive .15920 units for a total of 857 junior subordinated and GP
         units, both of which will also include attached CUs. A.G. Edwards
         estimates an implied value for these units of $15.41/unit.


  [  ]   The 2,396 subordinated units and 128 GP units currently owned by Petro
         will effectively be retired in the Transaction.


                                                                          Page 7

DESCRIPTION OF CONTINGENT UNITS

  [  ]   During the five year period, beginning with the first full four
         quarters following the Merger, the senior subordinated units, junior
         subordinated units and general partner interests will have the right to
         receive up to 909,000 senior subordinated units upon Petro meeting a
         "Contingent Unit Test." Each time the Contingent Unit Test is met, (but
         not more frequently than once every four quarter period), the senior
         subordinated units, junior subordinated units and general partner
         interests will receive an aggregate of 303,000 senior subordinated
         units, subject to a maximum of 909,000 senior subordinated units. The
         Contingent Unit Test will be met during any four quarter period when
         distributable cash flow per unit attributable to Petro exceeds $2.90
         which is 32% higher than the current annualized MQD of $2.20 and 26%
         higher than the proposed MQD of $2.30.

                                                                          Page 8

                                    profit margins) while making attractive 
                                    acquisitions

                        [_]   There are currently 6,383 Star Gas units
                              outstanding comprised of 3,859 common units, 2,396
                              subordinated units and 128 implied general partner
                              ("GP") units. The subordinated units and GP units
                              are currently assets of Petro.

                        [_]   There are currently 26,574 shares of Petro common
                              stock outstanding held by public shareholders and
                              "affiliates." The public holds 14,327 Class A
                              shares, 11 Class B shares and 282 Class C shares.
                              The "affiliates" hold 11,953 shares which include
                              9,638 Class A shares and 2,315 Class C shares.

                        [_]   Each shareholder of Petro will receive a certain
                              number of units in Star Gas such that the implied
                              consideration paid for each Petro share averages
                              $2.43 based on A.G. Edwards' estimates of the
                              value of the units being offered to Petro as
                              consideration.

                        [_]   All of the publicly held 14,327 Class A shares and
                              282 Class C shares, and a portion of the
                              "affiliate" held Class A shares (5,243) and Class
                              C shares (1,328) will receive .13064 units of
                              newly created senior subordinated units for each
                              share (1,908 units to the public and 859 units to
                              the "affiliates", 2,767 units in total) with an
                              attached Contingent Unit ("CU"). See the following
                              page for a discussion of the Contingent Units.
                              A.G. Edwards estimates an implied value for these
                              units of $18.52/unit (see page D-3). The remaining
                              "affiliates" of Petro not receiving senior
                              subordinated units, who hold a total of 5,382
                              shares, will receive .15920 units for a total of

                              which will also include attached CUs. A.G. Edwards
                              estimates an implied value for these units of
                              $15.41/unit (see page D-6).

                        DESCRIPTION OF CONTINGENT UNITS

                        [_]   During the five year period, beginning with the
                              first full four quarters following the Merger, the
                              senior subordinated units, junior subordinated
                              units and general partner interests will have the
                              right to receive up to 909,000 senior subordinated
                              units upon Petro meeting a "Contingent Unit Test."
                              Each time the Contingent Unit Test is met, (but
                              not more frequently than once every four quarter
                              period), the senior subordinated units, junior
                              subordinated units and general partner interests
                              will receive an aggregate of 303,000 senior
                              subordinated units, subject to a maximum of
                              909,000 senior subordinated units. The Contingent
                              Unit Test will be met during any four quarter
                              period when distributable cash flow per unit
                              attributable to Petro exceeds $2.90 which is 32%
                              higher than the current annualized MQD of $2.20
                              and 26% higher than the proposed MQD of $2.30.

[_] Certain analysis included in this presentation, including the calculations
    of the implied value of the senior subordinated, junior subordinated and GP
    units, require an estimate of the future price of the common units at
    Closing. To serve as a proxy for this future price, A.G. Edwards used the
    average common unit closing price for the last 20 trading days ended October
    14, 1998. Such price is 10.4% to 17.8% lower than the common units' implied
    unit value per the above analysis, and 3.6% greater than the common units'
    most recent closing price on October 14, 1998.

COMPARABLE TRANSACTIONS ANALYSIS
FIRM VALUATION

  [_]   A.G. Edwards noted that public disclosure regarding transactions in the 
        retail home heating oil distribution industry was extremely limited.

  [_]   A.G. Edwards analyzed the financial terms related to divestitures by
        Petro of certain of its retail home heating oil branches and compared
        them to the implied multiples of the aggregate purchase price of Petro's
        heating oil assets.

  [_]   Petro has sold three branches for an average EBITDA multiple of 9.0x.

  [_]   A.G. Edwards calculated the purchase price of Petro's heating oil assets
        and calculated multiples based on Petro's EBITDAs.

DISCOUNTED CASH FLOW ANALYSIS

[_]  A.G. Edwards performed discounted cash flow analyses for Petro, Star Gas
     and Star Gas Pro Forma using projected tax-adjusted operating cash flows
     for 1999 through 2002, terminal values calculated on 2002 EBITDA, and
     discount rates based on the related weighted average cost of capital.

Assumptions:

[_]  Weighted average cost of capital ("WACC")
     - Petro Stand Alone of 13.4% to 13.9% (calculated WACC of 13.6%)
     - Star Gas Stand Alone of 6.8% to 7.2% (calculated WACC of 7.0%)
     - Star Gas Pro Forma of 7.3% to 7.7% (calculated WACC of 7.5%)

[_]  Terminal value EB1TDA multiple
     - Petro Stand Alone of 6.0x to 8.0x (calculated normalized 1998 EBITDA
       multiple of 6.5x)
     - Star Gas Stand Alone and Star Gas Pro Forma of 9.0x to 11.0x (calculated
       normalized 1998 EBITDA multiple of 10.6x)

                                                                      Page H - 1

FIRM VALUATION

   [_]    A.G. Edwards noted that public disclosure regarding transactions in
          the retail home heating oil distribution industry was extremely
          limited.

   [_]    A.G. Edwards analyzed the financial terms related to divestitures by
          Petro of certain of its retail home heating oil branches and compared
          them to the implied multiples of the aggregate purchase price of
          Petro's heating oil assets.

   [_]    Petro has sold three branches for an average EBITDA multiple of 9.0x.

   [_]    A.G. Edwards calculated the purchase price of Petro's heating oil
          assets and calculated multiples based on Petro's EBITDAs.

FOR IMMEDIATE RELEASE

         STAR GAS PARTNERS, L.P. AND PETROLEUM HEAT AND POWER CO., INC.
                   ANNOUNCE AGREEMENT IN PRINCIPLE TO COMBINE


          STAMFORD, CT (August 14, 1998) - Star Gas Partners, L.P., ("Star" or
the "Partnership") (NYSE:SGU) and Petroleum Heat and Power Co., Inc. ("Petro" or
the "Company") (NASDAQ:HEAT), jointly announced today that they have reached an
agreement in principle to enter into a strategic business combination in which
Petro would become a wholly-owned subsidiary of Star.  This transaction would be
effected through Petro shareholders exchanging their approximately 26.6 million
shares of Petro Common Stock for approximately 3.6 million Star master limited
partnership units which will be subordinated to the existing Star Common Units.

Star Gas currently distributes to its partners, on a quarterly basis, all of its
Available Cash, which is generally all of the cash receipts of the Partnership
less all cash disbursements, with a targeted Minimum Quarterly Distribution
("MQD") of $0.55 per Unit, or $2.20 per Unit on an annualized basis.  In
connection with the Petro transaction, the Partnership will increase the MQD to
$.575 per unit or $2.30 per Unit on an annualized basis.  This increase in the
MQD reflects the expectation that the transaction will be accretive to the
Partnership.  The increase in the MQD will also serve to raise the threshold
needed to end the subordination period.

Of the 3.6 million subordinated Partnership units anticipated to be distributed
to Petro shareholders, 2.8 million will be Senior Subordinated Units and
approximately 857,000 will be Junior Subordinated Units and General Partnership
Interests.  The Senior
<PAGE>
 
Subordinated Units will be publicly registered and tradable (they are expected
to be listed on the NYSE) and will be subordinated in distributions to Star's
Common Units. The Junior Subordinated Units and General Partnership Interests
will not be registered nor publicly tradable and will be subordinated to both
the Common Units and the Senior Subordinated Units. The Senior Subordinated
Units will be exchanged with holders of Petro's publicly traded Class A common
stock and the Junior Subordinated Units and General Partnership Interests will
be exchanged with individuals that currently own Petro's Class C common stock.
Certain holders of the Company's Class C Common Stock will also exchange their
shares of Senior Subordinated Units.

It is currently contemplated that 21,177,000 shares of Petro Common Stock will
be exchanged for 2,767,000 Star Senior Subordinated Units.  5,386,000 shares of
Petro common stock, held by certain individuals who currently own Petro Class C
common stock, including Irik P. Sevin, Chairman of Petro and Star and other
members of a group that currently controls Petro, will be exchanged for 579,000
Junior Subordinated Units and General Partnership Interests which are
economically equivalent to 279,000 Junior Subordinated Units.

Under the partnership subordination provision, distributions on Star Senior
Subordinated Units may be made only after distributions of Available Cash on
Common Units meet the MQD requirement.  Distributions on Star Junior
Subordinated Units and to the General Partner may be made only after
distributions of Available Cash on Common Units and Senior Subordinated Units
meet the MQD requirement.  The Subordination Period will extend until the
Partnership earns and pays its MQD for three years.  In any event, as a
condition of this transaction, the Partnership agreement will be amended so that
no distribution will be paid on the Senior Subordinated Units, Junior
Subordinated Units, or to the General Partner except to the extent Available
Cash is earned from operations.

Like many other publicly traded master limited partnerships, the Partnerships
contains a provision which provides the General Partner with incentive
distributions in excess of certain targeted amounts.  This provision will be
modified so that should there be any such incentive distributions, they will be
made pro rata to the Senior Subordinated Units and Junior Subordinated Units as
well as to the General Partner.

In connection with the Transaction, the Senior Subordinated Units, Junior
Subordinated Units and General Partnership Interests can earn, pro rata, 303,000
additional Senior Subordinated Units each year that Petro provides $.50 per unit
accretion to Star to a maximum of 909,000 additional Senior Subordinated Units.

In connection with the transaction, Star intends to raise approximately $140
million through a public offering of Common Units and $120 million through a
public or private offering of debt securities.  The net proceeds from these
offerings will be used primarily to redeem approximately $240 million in Petro
public and private debt and preferred stock.  Any such offering will be made
only by means of a prospectus or in transactions not requiring registration
under securities laws.  This announcement does not constitute an offer to sell
any securities.  As part of this recapitalization, Petro also intends to
restructure $66.2 million of privately held notes.

Petro has reached an agreement with institutional holders of an aggregate of
$149 million or 63.1% of such public debt and preferred stock to permit there
redemption of such securities at the closing of the Star Gas/Petro Transaction.
This agreement allows Petro to redeem its 9 3/8% Subordinated Debentures, 10
1/8% Subordinated Notes and 12 1/4% Subordinated Debentures at 100%, 100% and
103.5% of principal amount, respectively, and to redeem its 12 7/8% Preferred
Stock at $23 per share.  In consideration for this early redemption right, Petro
has agreed to issue to such holders 3.37 shares of newly issued Petro Junior
Convertible Preferred Stock for each $1,000 in principal amount or liquidation
preference of such securities.  Each share of Petro Junior Convertible Preferred
Stock will be exchangeable into .13 of a Star common Unit at the conclusion of
this transaction representing a maximum 104,000 MLP units.  Should the
transaction not be consummated, the Junior Preferred Stock will be converted
into a like number of shares of Class A Common Stock.

Petro will offer to the remaining holders of it's publicly traded debt and
preferred stock the same right of early redemption under the same terms and
conditions as agreed to by the consenting holders.  This proposal will be made
through an exchange offer that is expected to commence shortly.  This
transaction and the associated Petro recapitalization are subject to receiving
an agreement to the early redemption from at least 90% of the outstanding
publicly traded debt and preferred stock.

Petro currently has a 40.7% equity interest in the Partnership and a subsidiary
of Petro is its general partner.  After completion of the transaction, the Petro
shareholders will own approximately 26% of Star's equity through Subordinated
Units and General Partnership Interests.  The holders of the Partnership's
Common Units (including an estimated 6.4 million Common Units that will be sold
in the Partnerships $140 million public offering) will own an aggregate
approximately 74% equity interest in the Partnership following the completion of
the transaction.  The General Partner of the Partnership will be a newly
organized Delaware limited liability company that will be owned by members of
Petro's current group.

In commenting on the proposed transaction, Joseph Cavanaugh, President of Star,
"We believe that this strategic combination will have a number of benefits for
the Partnership.  Firstly, we are pleased with having achieved our goal of
structuring a transaction which we believe will be immediately accretive,
enabling us to increase the Partnership's MQD to $2.30 annually.  Secondly, we
believe this strategic combination will provide an additional source of
attractive acquisition opportunities.  Petro is the largest retail heating oil
company in the country and the primary  consolidator of that highly fragmented
industry.  Over the past nineteen years Petro has acquired 189 distributorships.
As such, we believe this combination should provide the Partnership with a
platform to increase its acquisition activities.  Thirdly, over the past two and
one-half years, in an effort to take advantage of its size, Petro has
regionalized its operations, accessed developments in computer an and
communication technology, and  entered into cross-marketing partnerships.  These
programs have provided attractive productivity, operational and marketing
results which should continue to benefit the Partnership.  Finally, this
combination significantly increases the size and market capitalization of the
Partnership."

Irik P. Sevin, CEO of Petro stated, "We believe the proposed transaction will
enable Petro to achieve its stated objective of accessing equity to recapitalize
and delever.  This should permit us to continue our historically active
acquisition program and facilitate the funding of our operational and marketing
initiatives.  In addition, the MLP structure should provide a better valuation
format for Petro which is cash flow oriented and which has been the only
publicly traded company in its industry.  The transaction should provide our
shareholders with the resumption of annual cash distributions which Petro had
historically made."

The Board of Directors of Star has appointed an independent committee of
directors to represent Star Gas in this matter.  This committee has retained
A.G. Edwards & Sons, Inc. to act as it financial advisor and to determine the
fairness of this transaction to the Star Common Unit holders.  The Board of
Directors of Petro has retained PaineWebber Incorporated as its financial
advisor and Dain Rauscher Wessels to render an opinion as to the fairness to
Petro of this transaction.

The completion of the Transaction is subject to the negotiation and execution of
definitive agreements, the receipt of regulatory approvals, the approval of
Star's nonaffiliated common unit holders and Petro's nonaffiliated common
shareholders, other necessary partnership and corporate approvals, fairness
opinions from A.G. Edwards & Sons, Inc. and Dain Rauscher Wessels, and the
agreement to early redemption by the holders of 90% of Petro's

                                      -4-

publicly traded debt and preferred stock.

Petro and Star will continue to operate as separate business units and this
transaction will not have an impact on the day-to-day operations of either
entity.  There will be no reduction in the number of employees as a result of
this transaction.

Petroleum Heat and Power Co., Inc. is the largest retail distributor of home
heating oil in the nation, serving approximately 350,000 customers in the
